我们在制做辉光数码显示电路时,习惯上常常使用经过滤波的比较平滑的高压直流电源。它的主要优点是明亮而不闪烁,尤其适用于纪录性摄影。在实用中,有时也使用只经过整流而不滤波的高压脉动直流电作为辉光数码管阳极的简化电源。其效果也很好。虽然亮度略有损失,但数码管只要不在强烈阳光照射下使用,字形仍然是清晰明亮的。半波脉 We are in the system of glow digital display circuit, it is customary to use a relatively smooth filtered high-voltage DC power supply. Its main advantage is bright without flicker, especially for record photography. In practice, high voltage pulsating DC, which is rectified and not filtered, is sometimes used as a simplified power supply for the glow anode. The effect is also very good. Although a slight loss of brightness, but as long as the digital tube is not used in strong sunlight, the font is still clear and bright. Half-wave pulse
